Standard triaxial and repeated-load triaxial tests were conducted on the 5 granular materials used in the test sections. These tests were also conducted on CH subgrade clay having California Bearing Ratio (CBR) values of 4, 10, and 15. By closely following the protocol described in the ...
The test procedures comprise the measurement of soil permeability, CBR value, drained and undrained shear strength, and consolidation characteristics. Additional material in this new edition includes the Fall cone procedure for measurement of shear strength in clays based on the European Technical Specific...
Based on the results, the study proposes a preliminary procedure to derive the in situ correlation equation from that obtained from the in-mould laboratory tests in the CBR mould.doi:10.1016/j.trgeo.2016.12.002Ampadu, Samuel Innocent Kofi
The developed empirical correlations may be beneficial to approximate time consuming strength characteristic as well as physical properties at various locations within area under consideration using simple and rapid DCP test. KeywordCBR, DCP, OMC, MDD, PBTM. A. Patel...
Additionally, W-D cycles have a damaging effect on CBR values of Marginal aggregates (up to 55% reduction in CBR results after 16 cycles of W-D), whereas, CBR results of Premium aggregates show a subtle increase after conditioning. The W-D cycles also affect the properties of fine ...
If the CBR when the penetration amount is 5 mm was greater than the CBR when the penetration amount is 5 mm, then the test was redone, and if the result was still the same, the CBR at 5 mm was used. 2.2.2. Resilient Modulus Test The test procedure of the resilience modulus is as...
The Brazilian test (BTS) method suggested by the ISRM (1978) was used to measure the indirect tensile strength (σt) on a CBR-Marshal 50 kN (Figure 4a) loading machine with a displacement-controlled rate of 0.003 mm/s so that samples failed at between 30 and 60 s. Samples were placed...
The same experimental procedure is performed on these samples. Those samples had been taken from the same type of containers as those used in environmental stability tests and had been sampled every two weeks over the summer. Table 2 presents the sampling dates and the physicochemical properties ...
